Research by University of Toronto scientists offers novel insights into why and how wind-pollinated plants have evolved from insect-pollinated ancestors, and what it might mean for a potential pollination crisis. They found that plants in which stamens vibrate more vigorously in wind, disperse pollen by wind more readily, and that this characteristic of stamens is favoured under conditions where plants receive few visits from pollinators.

Rice University scientists develop protein switches that can be used to control the flow of electrons within cells. The synthetic proteins are one of the few remaining components needed to mimic entire electronic devices within cells.

Does expansion microscopy deliver true-to-life images of cellular structures? That was not sure yet. A new publication in Nature Methods shows for the first time that the method actually works reliably.

A new quantum algorithm has been implemented for quantum chemical calculations such as Full-CI on quantum computers without exponential/combinatorial explosion, giving exact solutions of Schroedinger Equations for atoms and molecules, for the first time.

When humans experience stress, their inner turmoil may not be apparent to an outside observer. But many animals deal with stressful circumstances -- overcrowded conditions, not enough food -- by completely remodeling their bodies. These stress-induced forms, whether they offer a protective covering or more camouflaged coloration, can better withstand the challenge and help the animal survive until conditions improve.

Physicists are now exploring laser-based technology traditionally used for studying conditions in the atmosphere -- such as Light Detection and Ranging (LIDAR) -- to shine a light on the subtlest of features of mosquito activity and better track populations that may carry a viral threat.
